With @jeromevalette.bsky.social & Jesús Fernández-Huertas Moraga, we are happy to announce the CfPapers for the

4th edition of the Junior Workshop on the Economics of Migration

on May 26-27, 2026 @uc3meconomics.bsky.social, Spain.

Submit until February 1, 2026 on economig2026.sciencesconf.org

I’m very happy to see our paper published in Political Geography. We show that your country of residence influences your waiting time for an appointment at a German diplomatic mission. These differences are substantial and far from random.

Zitat von Dr. Niklas Harder: Wartezeiten auf Termine an deutschen Auslandsvertretungen sind die erste Hürde auf dem Weg nach Deutschland. Unsere Untersuchung zeigt, dass das Herkunftsland entscheidet, wie hoch diese Hürde ist. Gute Migrationspolitik braucht Transparenz und gleiche Chancen für alle motivierten Einwanderer*innen, egal aus welchem Land. Hier bietet sich eine öffentlich zugängliche Plattform mit den aktuellen Wartezeiten an, etwa als Teil des Auslandsportals des Auswärtigen Amtes. Transparenz ist auch die Grundlage dafür, die Frage zu diskutieren, wie die unterschiedlichen Wartezeiten entstehen.

Langes Warten oder kein Termin – Globaler Süden wird im dt. #Visasystem deutlich benachteiligt. Das zeigt die Analyse von @deutschmann.bsky.social, @eui-eu.bsky.social, @niklas-harder.bsky.social & @alexandra-orlova.bsky.social @politicalgeography.bsky.social

Migration needs more common ground!?

Glad to join Konrad's excellent "Migration Debates" on the importance of compromise with Marc Helbling and Oliviero Angeli.

The interviews are available in English (and German) here:
www.kas.de/en/web/analy...

Interesting how there really isnt much variation across the major platforms.

uuh...I love it! We submit our paper in approx. 2 weeks. If something is citable by then, we make sure to include it.

I heard there are things based on "ANES" data in the US but I cant find a citable paper. Any help much appreciated.

Looking for studies that show memership composition in terms of "political idealogy/ party preferences" of large social media platforms. Any hints?

American Journal of Political Science | MPSA Journal | Wiley Online Library Concern that immigration worsens crime problems is prevalent across Western publics. How does it shape electoral politics? Prior research asserted a growing left–right divide in immigration attitudes...

Glad to see this out at @ajpseditor.bsky.social! I show that the immigration-crime issue, when salient, can shift leftist cosmopolitans to the Right. This is due to leftist voters being more conservative on crime than leftist parties.

thanks for the invite @conradziller.bsky.social

that AFD has higher visibility among neutral, and apolitical new users on TikTok. AFD has even higher advantage among users who are interested in info about the election. We finds consistent results for regional and federal election

Great time back at my alma mater @freieuniversitaet.bsky.social presenting our (@unipotsdam.bsky.social) research on exposure to political content on #tiktok at AK-Wahlen.

In a nutshell, we find....

Here’s the partisan lean of platform audiences, 2020 → 2024.

📊 Instagram, TikTok, Reddit stay solidly Dem.
📊 Facebook & YouTube: modestly rightward.
📊 Twitter/X: sharpest move right.
📊 “Other” (Threads, Bluesky, etc.): flipped hard from red to blue.

The sorting is unmistakable.

Search LibGen, the Pirated-Books Database That Meta Used to Train AI Millions of books and scientific papers are captured in the collection’s current iteration.

Just a reminder to check for your name in this list of books that OpenAI trained from. If your name is there, they probably owe you several thousand dollars.

OpenAI cried that if everyone eligible author files, the company will go bankrupt, so I'm alerting every author I have ever spoken to.

The Potsdam Social Media Monitor (psmm.info) measured which parties new, unpolitical users are exposed to more often. Maybe unsurprisingly, #Afd dominates. We delve into the reasons why.

Excited to present our paper on exposure to right-wing political content on #TikTok at @wzb.bsky.social conference "The future of democracy on 8-10 October.
